It's so lonely to feel the way you do. I've felt the same. It's difficult to listen to others so easily telling you to be active when you just don't feel it. It's hard but sometimes you will have to push yourself. I do. A little fake it until you make it. The times I make the effort show me that it can be done and what life is like when you can get past things and try.
It takes a lot of energy-it is exhausting sometimes- to get your head in the game but I feel successful when I Am in the game,rather than not... I am writing this now after spending the weekend sitting at home with only a few purposeful outings. But that's not what I want so I know I am the one who will have to change if I want my situation to change.
It's small steps and some setbacks to figure out along the way but try to look at the positives, whatever they may be. All the best.
